Furthermore, there is no intention to be bound by any theorypresented in the preceding background of the invention or the followingdetailed description.

The embodiments of the present disclosure disclose a joystick feedbackforce device of a gamepad to improve the hand feel in operating thejoystick.

The technical solutions in the embodiments of the present disclosurewill be clearly and completely described below in conjunction with thedrawings and specific embodiments. Obviously, the embodiments describedare only part of, rather than all of, the embodiments of the presentdisclosure. Based on the embodiments in the present disclosure, allother embodiments obtained by a person of ordinary skill in the artwithout paying creative work shall fall within the protection scope ofthe present disclosure.

Please refer to FIG. 2 to FIG. 4 . FIG. 2 is a schematic view of thestructure of a joystick feedback force device of a gamepad according toa specific embodiment of the present disclosure; FIG. 3 is a schematicview of providing an assisting force; FIG. 4 is a schematic view ofproviding a resisting force.

In the specific embodiment, the joystick feedback force device of thejoystick according to the present disclosure comprises a joystick 1 anda torque output device 4.

The joystick 1 is installed in a casing 2 of the gamepad, and can accepta user's operation and rotate relative to the casing 2. Namely, thejoystick 1 is rotatably installed in the casing 2. Specifically, it canrotate relative to the casing 2 around an X-direction and a Y-directionthat are perpendicular to each other. The installation mode of joystick1 and casing 2 may refer to the prior art and will not be described indetail here. The top end of the joystick 1 generally protrudes from thecasing 2 to facilitate accepting the user's operation and swinging alongwith the user's operation.

The torque output device 4 is installed in the casing 2 and isconfigured to output a torque. The output end of the torque outputdevice 4 is connected with a rotating shaft 3 of the joystick 1, so atorque is applied to the rotating shaft 3, thereby forming a feedbackforce, i.e., an assisting force or a resisting force to the rotation ofthe joystick 1. When the joystick 1 is rotatably installed in the casing2, it has the rotating shaft 3. The output shaft of the torque outputdevice 4 is connected with the rotating shaft 3 of the joystick 1, andthus the output shaft can apply a torque to the joystick 1. The outputshaft of the torque output device 4 may be directly and fixedlyconnected with the rotating shaft 3 of the joystick 1, or may beindirectly connected with it via a deceleration device, etc. which maybe set as required, and there is no limitation here. The torque outputdevice 4 may be a motor or other conventional equipment that can outputa torque.

According to the joystick feedback force device of the gamepad of thepresent disclosure, when the user operates the joystick 1 to rotate, acertain torque is output from the output shaft of the torque outputdevice and applies to the rotating shaft 3 of the joystick 1, namely,the corresponding torque is applied to the joystick 1 to form a feedbackforce to the user. Therefore, in the process of operating the joystick1, the user can not only feel the action on the joystick 1 by means ofthe controlled object on the screen, but also directly feel the feedbackforce provided by the joystick 1 itself, and thus obtain a good handfeel in operation.

In order to realize the automatic control of the torque output device 4,a control module may be provided and connected with the torque outputdevice 4. When the user rotates the joystick 1, the rotation directionof the joystick 1 can be detected by a sensor. For example, by providinga displacement sensor 5, when the user toggles the joystick 1 togenerate a displacement, the displacement sensor 5 detects the positionchange of the joystick 1 and sends a signal to the control module, andthe control module controls the torque output device 4 to output atorque.

Specifically, the torque output by the torque output device 4 isadjustable. The “torque is adjustable” mentioned here and below refersto that the magnitude and/or direction of the output torque isadjustable. The “direction is adjustable” means that the torque outputdevice 4 can output clockwise rotation or counterclockwise rotation; the“magnitude is adjustable” means that the magnitude of the torque outputby the torque output device 4 is adjustable. The torque output device 4may specifically comprise a linear motor, and the output torque can beadjusted by adjusting the current passing through the linear motor. Forexample, when it is necessary to provide an assisting force in thedirection consistent with the direction in which the user operates thejoystick 1, a current in a certain direction is provided to the linearmotor to apply the assisting force. When it is necessary to provide aresisting force in the direction opposite to the direction in which theuser operates the joystick 1, a current in a reverse direction isprovided to the linear motor to apply the resisting force to thejoystick 1. When it is necessary to adjust the magnitude of the feedbackforce (such as an assisting force or a resisting force), the magnitudeof the output torque can be adjusted by adjusting the magnitude of thecurrent passing through the linear motor, thereby realizing theadjustment of the magnitude of the feedback force. When a control moduleis provided, the torque output by the torque output device 4 can beadjusted automatically by the control module. For example, the directionand magnitude of the current passing through the torque output device 4may be automatically controlled by a digital circuit, thereby realizingthe adjustment of the output torque. If necessary, the direction andmagnitude of the current passing through the torque output device 4 maybe controlled by manually adjusting the direction and capacity of apower supply externally connected with the torque output device 4,thereby realizing the adjustment of the output torque. By adjusting thetorque output by the torque output device 4, the feedback force can beadjusted to meet the different feedback force needs of users. Forexample, for different users, the feedback force of joystick 1 can beadjusted conveniently according to their personal habits, therebyfurther improving the hand feel in operating the joystick 1.

Specifically, the output shaft is fixedly connected with the rotatingshaft 3 of the joystick 1. That is, the output shaft is directly andfixedly connected with the rotating shaft 3 of the joystick 1, anddirectly applies a torque to the rotating shaft 3. For example, theoutput shaft and the rotating shaft 3 may be connected by directwelding, pin connection, clamp connection or bolt connection. Of course,if necessary, the output shaft may also be fixedly connected with therotating shaft 3 of the joystick 1 by other conventional connectionmodes in the prior art.

In the above embodiments, the rotating shaft 3 of the joystick 1comprises an X-direction rotating shaft and a Y-direction rotating shaftthat are perpendicular to each other, and the joystick 1 can rotaterelative to the casing 2 around an X-direction and a Y-directionrespectively. The torque output device 4 comprises an X-direction torqueoutput device connected with the X-direction rotating shaft and aY-direction torque output device connected with the Y-direction rotatingshaft. In other words, the joystick 1 can rotate relative to the casing2 around the X-direction and the Y-direction; when the joystick 1rotates relative to the casing 2 around the X-direction, the rotatingshaft 3 of the joystick 1 is the X-direction rotating shaft; when thecorresponding joystick 1 rotates relative to the casing 2 around theY-direction, the rotating shaft 3 of the joystick 1 is the Y-directionrotating shaft. Since the joystick 1 can rotate around differentdirections, correspondingly, the X-direction torque output device andthe Y-direction torque output device are provided corresponding to theX-direction rotating shaft and the Y-direction rotating shaftrespectively, so as to provide a feedback force for X-direction rotationand Y-direction rotation of the joystick 1 respectively. If necessary,only the X-direction torque output device may be provided or only theY-direction torque output device may be provided, and the feedback forceis only provided in the corresponding direction.

Further, the Y-direction rotating shaft remains stationary when theX-direction rotating shaft rotates relative to the casing 2, and theX-direction rotating shaft remains stationary when the Y-directionrotating shaft rotates relative to the casing 2. In other words, whenthe joystick 1 rotates around the X-direction, it will not interferewith the Y-direction rotating shaft. Similarly, when the joystick 1rotates around the Y-direction, it will not interfere with theX-direction rotating shaft. Specifically, it can be achieved through therotatable installation mode of the joystick 1. The specific installationstructure may refer to the rotatable installation mode of theconventional joystick 1 in the prior art, which will not be described indetail here. Of course, when the X-direction rotating shaft rotatesrelative to the casing 2, if the Y-direction rotating shaft moves alongwith the X-direction rotating shaft, it only needs to reserve a movementspace in the casing 2 for the Y-direction torque output device; when theY-direction rotating shaft rotates relative to the casing 2, if theX-direction rotating shaft moves along with the Y-direction rotatingshaft, it only needs to reserve a movement space in the casing 2 for theX-direction torque output device correspondingly.

On the basis of the above embodiments, it further comprises a controlmodule that is electrically connected with the torque output device 4,and the control module is configured to control a direction and/or amagnitude of the torque output by the torque output device 4 accordingto the game information. Specifically, the control module generatescorresponding control commands according to the game information andcontrols the direction and/or the magnitude of the torque output by thetorque output device 4. The direction of torque corresponds to theforward or reverse rotation of the output shaft of the torque outputdevice 4. If necessary, the control module may control the direction ofthe output torque alone according to the game information, or controlthe magnitude of the output torque alone, or control the magnitude anddirection of the output torque at the same time. By adjusting themagnitude and direction of the torque output by the torque output device4, the direction and magnitude of the corresponding feedback force ofthe joystick 1 are adjusted. Specifically, the control module may be acontroller. In sum, by providing the control module, specifically, bycombining a digital circuit with game scenes, the magnitude or directionof the torque output by the torque output device 4 can be controlledaccording to the game information at any time. Specifically, theadjustment of the direction of the output torque can be achieved bycontrolling the direction and magnitude of the current passing throughthe torque output device 4.

Specifically, the control module is configured to control the rotationdirection of the torque output to the joystick 1 from the torque outputdevice 4 to be the same as the rotation direction of the joystick 1 inscenes of smooth roads, downhill slopes or skiing, and to control therotation direction of the torque output to the joystick 1 from thetorque output device 4 to be opposite to the rotation direction of thejoystick 1 in scenes of wind, rain or hill climbing. Of course, thecontrol mode of the control module corresponding to different gamescenes is not limited to the above situations, and can be set accordingto actual needs of game scenes.

When the user rotates the joystick 1, the rotation direction ofjoystick1 can be detected by a sensor. For example, by providing a displacementsensor 5, when the joystick 1 is pushed by the user to generate a smalldisplacement, the displacement sensor 5 detects the position change ofthe joystick 1 and sends a signal to the control module, and the controlmodule controls the torque output device 4 to output a correspondingtorque according to the game information. For example, when an assistingforce needs to be output according to the game information, the rotationdirection of the torque output from the torque output device 4 to thejoystick 1 is the same as the rotation direction of the joystick 1; whena resisting force needs to be output according to the game information,the rotation direction of the torque output from the torque outputdevice 4 to the joystick 1 is opposite to the rotation direction of thejoystick 1. Take the case that the torque output device 4 is a motor asan example, when an assisting force needs to be output according to thegame information, the control module controls the rotation direction ofthe motor so that the rotation applied to the joystick 1 shares the samerotation direction with the joystick 1. Specifically, the rotationdirection of the motor may be controlled by controlling the direction ofthe current passing through the motor, that is, by controlling so that acurrent in a certain direction is applied to the motor; at the sametime, the magnitude of the assisting force may be controlled bycontrolling the magnitude of the current passing through the motor. Whena resisting force needs to be output according to the game information,the control module controls the rotation direction of the motor so thatthe rotation direction of the rotation applied to the joystick 1 isopposite to the rotation direction of the joystick 1. Specifically, therotation direction of the motor can be controlled by controlling thedirection of the current passing through the motor, that is, bycontrolling so that a reverse current is applied to the motor; at thesame time, the magnitude of the resisting force may be controlled bycontrolling the magnitude of the current passing through the motor.Specifically, the magnitude and the direction of the current input intothe motor may be controlled by a program, thereby obtaining differentfeedback forces in different game scenes and improving the user's gameexperience.

It can be seen that, by controlling the direction of the torque outputby the torque output device 4 according to the game information by thecontrol module, the automatic adjustment of the feedback force of thejoystick 1 as an assisting force or a resisting force can be realized,and by controlling the magnitude of the torque output by the torqueoutput device 4 by the control module, the corresponding automaticadjustment of the magnitude of the assisting force or resisting forcecan be realized, so that different feedback forces can be obtained indifferent game scenes and the operator's hand feel can be improved.

In the above embodiments, it further comprises an adjustment moduleconfigured to accept the user's operation and generate a correspondingadjustment signal. The adjustment module is electrically connected withthe torque output device 4, and the torque output device 4 is configuredto control the direction and/or magnitude of the output torque accordingto the adjustment signal. That is, by providing the adjustment module toaccept the user's adjustment operation and generate a correspondingadjustment signal, the torque output device 4 controls the directionand/or magnitude of the output torque according to the receivedadjustment signal. Thus, the user can conveniently adjust the directionor magnitude of the feedback force of the joystick 1 according to hisown habits to obtain a hand feel suitable to himself

Specifically, the adjustment module may be electrically connected withthe torque output device 4 via a control module, that is, the adjustmentmodule receives the user's adjustment operation and generates acorresponding adjustment signal, and the control module adjusts thedirection and/or magnitude of the torque output by the torque outputdevice 4 according to the received adjustment signal. The adjustmentmodule may specifically comprise a touch screen to accept the user'sadjustment operations such as a touch. Alternatively, the adjustmentmodule may comprise a knob to accept the user's adjustment operationssuch as rotation. Take the case that the torque output device 4 is amotor as an example, the user may specifically adjust the torque outputby the motor by adjusting the magnitude of the current passing throughthe motor, thereby generating different magnitudes of feedback force tothe operator.

In sum, by providing the adjustment module and the control module, indifferent game scenes, the magnitude and direction of the current can beadjusted at any time by combining the digital circuit with game scenes,and different assisting force and resisting force can be applied to thejoystick 1 according to the game scenes, thereby obtaining differentfeedback forces in different game scenes and improving the operator'shand feel. Moreover, players can adjust the magnitude of the feedbackforce of joystick 1 according to their personal habits to obtain a handfeel suitable to themselves.

In the above embodiments, it further comprises a position restoringelastic member disposed between the joystick 1 and the casing 2 forreturning the joystick 1 to its original position. In other words, byproviding the position restoring elastic member, when the user releasesthe joystick 1, the joystick 1 can return to its original position(typically, a center position of swinging) under the action of theposition restoring elastic member. Of course, when the positionrestoring elastic member is provided, the position restoring elasticmember itself can also provide a certain feedback force, so the user canadjust the torque output by the torque output device 4 as required, andby combining it with the feedback force of the position restoringelastic member, a comprehensive hand feel suitable to the user can beobtained.
